| Abstract: | The renewal of 4 BFs at Shougang Corp. were conducted in succession during the period from 1991 to 1994. In order to increase coal ratio and decrease coke ratio of BFs,a series of measures were adopted, such as improving material quality, optimizing BF operation parameters, injecting pulverized coal with oxygen enriched blast,enhancing blast temperature and so on. As a result ,good effect was achieved,the coke ratio of BFs decreased by 140. 5 kg/t and the coal ratio increased by 85. 7 kg/t in the first half of 2002 compared with 1995. |
